Is possible to have a custom screen mode 1366x768 on an o2 ?.
Maybe some one have try it or already done ?.

Should be. What display is this for? It's generally best to try to match the modeline/edid data for the specific monitor.

Lots more info on custom video formats here (note vfc is not installed by default in Irix): https://wiki.preterhuman.net/Video_Forma...VFO)_Files.

If you send me the monitor info I can probably get something working in a few days.

It is.  I run 1600x900 oddly enough. I can post my vfo file tomorrow if it helps. [I literally just powered the o2 down :( ]

Added: Below are the 2 pieces I used to generate my 1600x900 custom resolution. The trick is to look up your monitor specs create a VFS file using them (name it you monitor type so you remember) then generate your vfo file using the vfc.command it will move it place for you.

my vfc.command file

#!/bin/sh
/usr/sbin/vfc -c chip=/usr/gfx/ucode/vfc/rules/O2_Chip.def,board=/usr/gfx/ucode/vfc/rules/O2_Board.def HP2009M.vfs
mv a.vfo /usr/gfx/ucode/CRM/vof/1600x900_60.vfo
